aight, first off, jahangir is wrong. ghost hitting is bad for you dude.

now, as far as smoking in your apartment, I have the same problem. I usually just grab a seat by my window and blow it out the window. I too live on the second floor, so no one really notices / cares. Plus most of the people living around me are also college students and don't give two fucks about the smell. If that's the case, fuck all this "doob tube" shit and just sit back on the cound and roast a bowl, bong, whatever. But like you said, cops are everywhere, so I would try and smoke elsewhere, but if you had to, just blow smoke out of a window discretely and you should be good.
